Gallic civilization had then advanced as far as the native political incapacity of the Gauls would permit. Quick-witted and intelligent, they were to gain from Rome the discipline they needed. Once accustomed to the enforcement of a stable order, their finer qualities responded by a ready acceptance of the benefits of civilization and a rapid appropriation of Latin culture. Not a sentence of the Gallic literature survives. But that this people were endowed with eloquence and possessed of a sense of form, was to be shown by works in their adopted tongue.[147] Romanized and Latinized, they were converted to Christianity and then renewed with fresh Teutonic blood. So they enter upon the mediaeval period; and when, after the millennial year, the voices of the Middle Ages cease simply to utter the barbaric or echo the antique, it becomes clear that nowhere is there a happier balance of intellectual faculty and emotional capacity than in these peoples of mingled stock who long had dwelt in the country which we know as France. Since the Celts of Gaul have left no witness of themselves in Gallic institutions or literature, it is necessary to turn to Ireland for clearer evidence of Celtic qualities. There one may see what might come of a predominantly Celtic people who lacked the lesson of Roman conquest and the discipline of Roman order. The early history of the Irish, their presentation of themselves in imaginative literature, their attainment in learning and accomplishment in art, are not unlike what might have been expected from Caesar’s Gauls under similar conditions of comparative isolation. Irish history displays the social turmoil and barbarism resulting from the insular aggravation of the Celtic weaknesses noticeable in Caesar’s sketch; and the same are carried to burlesque excess in the old Irish literature. On the other hand, Irish qualities of temperament and mind bear such fair fruit in literature and art as might be imagined springing from the Gallic stem but for the Roman graft.[148] No trustworthy story can be put together from the myth, tradition, and conscious fiction which record the unprogressive turbulence of pre-Christian Ireland. But the Irish character and capacities are clearly mirrored in this enormous Gaelic literature. Truculence and vanity pervade it, and a passion for hyperbole. A weak sense of fact and a lack of steady rational purpose are also conspicuous. It is as ferocious as may be. Yet, withal, it keeps the charm of the Irish temperament. Its pathos is moving, even lovely. Some of the poetry has a mystic sensuousness; the lines fall on the ear like the lapping of ripples on an unseen shore; the imagery has a fantastic and romantic beauty, and the reader is wafted along on waves of temperament and feeling.[149]
